Abstract

The utility model discloses a cab supporting rod structure which comprises an upper supporting rod and a lower supporting rod. The upper supporting rod and the lower supporting rod are hinged mutually, one end of the upper supporting rod fixes an upper supporting rod support, one end of the lower supporting rod fixes a lower supporting rod support, the lower supporting rod support comprises a first fixing portion, a second fixing portion and a web, and the two sides of the web are curled to form an arc portion. Stress borne by the lower supporting rod support is more uniform, and the cab supporting rod structure effectively prevents the problem that the lower supporting rod support is prone to being deformed in use.

Description

The operator's compartment supporting bar structure

Technical field

The utility model relates to a kind of operator's compartment supporting bar structure.

Background technology

General operator's compartment supporting bar structure comprises upper support bar and lower support bar, upper support bar and lower support bar are hinged, at the fixing strut upper bracket of an end of upper support bar, existing strut lower support structure as shown in Figure 1, comprise the first fixed part 1, the second fixed part 2 and the web 20 that is connected described the first fixed part 1 and described the second fixed part 2, web 20 cross sections are roughly V-shaped, web being carried out to the stress test analysis, be to find, between web V-type trench bottom A place is for 2 to 3 times at V-type groove both sides (being position, accompanying drawing B place) stress, cause web easily to be out of shape, therefore be necessary to make improvements.

Summary of the invention

For the deficiencies in the prior art, the utility model provides the operator's compartment supporting bar structure, and web intensity is higher, is not easy distortion.

The utility model is achieved by the following technical solution: a kind of operator's compartment supporting bar structure, comprise upper support bar and lower support bar, described upper support bar and lower support bar are hinged, at the fixing strut upper bracket of described upper support bar one end, at the fixing strut lower bracket of described lower support bar one end, described strut lower bracket, comprise the first fixed part, the second fixed part and web, and described web both sides curl into arc sections.

The utlity model has following beneficial effect: it is more even that the strut lower bracket is subject to stress, effectively prevented that in use the strut lower bracket holds yielding problem.

The accompanying drawing explanation

The structural representation that Fig. 1 is strut upper bracket in background technology.

The structural representation that Fig. 2 is the utility model operator's compartment strut bar.

The structural representation that Fig. 3 is the utility model upper bracket.

The structural representation that Fig. 4 is the utility model lower bracket.

The specific embodiment

Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail: referring to figs. 2 to Fig. 4, a kind of operator's compartment supporting bar structure, comprise upper support bar 1 and lower support bar 2, described upper support bar 1 and lower support bar 2 are hinged, at the fixing strut upper bracket 3 of described upper support bar 1 one ends, at the fixing strut lower bracket 4 of described lower support bar 2 one ends, it is characterized in that: described strut lower bracket 4, comprise the first fixed part 40, the second fixed part 41 and web 42, described web 42 both sides curl into arc sections 42a.

In identical test condition effect, be subject to stress intensity at the utility model web 42 A places, middle part and be about 418MP, the stress intensity that B place, both sides is subject to is about the 500MP(original design web middle part stressed 804MP of being about in A place, the stressed about 400MP in both sides), therefore stressed less, be not easy to cause distortion.

Referring to Fig. 3, described strut upper bracket 3 comprise for fixing the first plate body 30 of described upper support bar 1 and vertical welding in the second plate body 31 of described the first plate body 30, offer the first through hole 30a at described the first plate body 30 middle parts, at described the second plate body 31 middle parts, offer the second through hole 31a.Described the second plate body 31 upsides are recessed to form depressed part 31b downwards.

The stress be subject in depressed part 31b and the first through hole 30a and the second through hole 31a position is very little, therefore adopts said structure in the situation that do not affect normal use, has effectively reduced the consumption of material, has reduced the productive costs of product.

Claims

1. an operator's compartment supporting bar structure, comprise upper support bar (1) and lower support bar (2), described upper support bar (1) and lower support bar (2) are hinged, at the fixing strut upper bracket (3) of described upper support bar (1) one end, at the fixing strut lower bracket (4) of described lower support bar (2) one ends, it is characterized in that: described strut lower bracket (4), comprise the first fixed part (40), the second fixed part (41) and web (42), described web (42) both sides curl into arc sections (42a).
